11 Claims. 1

This invention relates to new and useful improvements in attachments forexercising machines, and more particularly to attachments for exercisingmachines of the type and construction disclosed in United States LettersPatent for Exercising Machine No. 2,565,348, issued August 21, 1951.

The principal object of the present invention is to provide anattachment for exercising machines of the type described which, whenused in conjunction with such machines, effectively provides for theexercise and stretching of the muscles in the arms of a person, andparticularly the muscles which control bending of the elbow.

Another object of the invention is to provide an attachment forexercising machines of the stated type which may be readily adjusted tomeet the needs of individuals with functional limitations as well as therequirements of different sizes of persons.

A further object of the invention is to provide an attachment having theforegoing features and characteristics which is of relatively simplifiedconstruction and highly efficient and effective in use.

These and other objects of the invention and the various features anddetails of the construction and usethereof are hereinafter fully setforth and described with reference to the accompanying drawing, inwhich:

Fig. l is a view in perspective showing an attachment made according tothe present invention in cooperating association with an exercisingmachine of the aforesaid type and construction;

Fig. 2 is a side elevational view of the attachment; and

Fig. 3 is a fragmentary sectional view in reduced scale on line 3-3,Fig. 2.

Referring now more particularly to the drawing, an attachment made inaccordance with the present invention is shown in conjunction with anexercising machine of the construction described in United StatesLetters Patent No. 2,565,348, aforesaid. Such a machine embodies ahollow base structure In including a continuous enclosing side wallportion, a relatively fixed seat 12 and a mounting means 13 which ismounted for oscillatory movement toward and away from the seat I2 andadapted for mounting thereon a handle structure (not shown).

An attachment made in accordance with the present invention comprises abase plate 15 which is adapted to rest upon the floor-and underlie theforward end portion of the machine base It, for example, in the relationshown in Fig. 1 of the drawing. Provided on the upper surface of thebase plate I5 is a plurality of suitably arranged clamping devicesconstructed and arranged as described in applicants co-pendingapplication Serial No. 202,949, filed December 27, 1950, for securingthe attachment fixedly with respect to the base H3 of the exercisingmachine. Secured adjacent the outer end of the base plate l5 andinclined outwardly with respect to the exercising machine is anupstanding tubular stanchion that is braced by means of angular- 1yextending elements 2|, 2! which have their upper ends secured to thestanchion 20 and their lower ends secured to the base plate l5.

Telescopically received within the tubular stanchion 20 is a stud 22.The stud 22 is adjustable in the stanchion 20 and this is accomplishedby providing a series of openings in the stud and a correspondingopening in the stanchion 20 for passage of a pin 23 through a selectedopening in the stud 22.

Pivotally connected to the upper end of the justably mounted on themounting means 13 a split sleeve or collar 25 having a set screw 21therein for securing the sleeve or collar 26 in a selected position onthe means connected, as indicated at 28, to a boss 29 on the sleeve orcollar 25 is one end of a shaft member 3!] which has its other-endportion telescopically received within one end of a tubular member 3!that is split and provided. with a set screw 32 for securing the shaftand tubular members and 3|, respectively, in a selected telescopicrelation with respect to each other. The other end of the tubular member3! is pivotally connected as at 33 to a boss 34 on a split collar 35which is mounted on the rod support 25 and provided with a set screw 33for locking the collar 35 in any desired position for adjustmentlengthwise along said rod support 25.

Telescopically received within the upper end of the rod support 25 isthe shank portion 3'! of a handle bar 38 which is provided with handgrip portions 39 'on its opposite ends. The shank 31 of the handle 38 isadjustable telescopically with respect to the rod support 25 and this isaccomplished by providing a series of openings in I 3. Pivotally theshank portion 31 and an opening in the rod support 25 for the passage ofa pin 40 through a selected one of the openings in the handle stud 31.

The attachment is used in the manner illustrated in Fig. l of thedrawing of an exercising machine of the type referred to previouslyherein. By selective: adjustment of the handle shank 31 in rod support25 and of stud 22 in the stanchion 20, the attachment may be properlyset according to the size of the particular person the telescopioconnection of .themembers Ell-and.

fit-With respect to each other, the position of' the rodisupportfiiandhandie 38, angularly to the rightand left of the position shown inFig. 2 ofthe drawing, maybe? varied within the limits of extensionandcontraction of the telescopically adjustable members" 30. and 31:When the attachment has been properly adjusted for the size of theperson and forrthe' desired arc of oscillatory movementao'tthe' handle38, as described, the person intending to use the device sitsbeside'the-attachment, as shown in Fig. 1, and places' hisor-herhand on oneof'th'e hand grips 39 of the handle 38. The motor ofithe exercisingmachine may then' bestarted and 1e resulting oscillatory movementimparted to: the handle' 33 f the attachment operates effec tively to"exercise and: stretch the muscles in the persons arm.

While a particularembodim'ent of theinventionhas been illustrated anddescribed herein it isnot intended that the invention be limited to suchdisclosure and'changes and modifications may be madewithin the scope ofthe following claims.
